Well I can make a personal list which reflects the inventions that have made the biggest difference for me personally:

• the contraceptive pill: I wouldn't be childless without it!

• the internal combustion engine: in the long term it allowed the developed of mass travel which allowd poor people like me to travel the world

• the Internet: can you remember how small life was when your main source of information was the local library
• electric light - having just pet some time camping I will never be cavalier about good light again
• refrigeration is pretty cool too - keeps you and the food cool!
• artivfical fibres like Lycra and nylon - I hate ironing
• the automatic washing machine - have you ever tried to wash sheets by hand or using a twin-tub!
